A CONCISE statement of the develop- 

 ment of the human body and a foun- 

 dation for the proper understanding 

 of the facts of anatomy. The comparative 

 anatomy and development of the lower ani- 

 mals, too, is constantly referred to, a different 

 style type being used for these references. 



The assimilation of the enormous mass of 

 facts which constitute what is usually known 

 as descriptive anatomy has always been a 

 difficult task for the student. Part of the 

 difficulty has been due to a lack of informa- 

 tion regarding the causes which have de- 

 termined the structure and relations of the 

 parts of the body, for without some knowl- 

 edge of the " why" things are so, the facts of 

 anatomy stand as so many isolated items, 

 while with such knowledge they become 

 bound together to a continuous whole and 

 their study assumes the dignity of a science. 

 The great key to the significance of the 

 structure and relations of organs is their de- 

 velopment, recognizing by that term the his- 

 torical as well as the individual development

A Laboratory Text-Book 

 of Embryology 



By Charles S. Minot, S. D., LL D. 



Professor of Histology and Human Em- 

 bryology, Harvard University 

 Medical School. 



With 218 Illustrations, mainly original. 

 Quarto; 380 pages. Cloth, $4.50 net. 



This work is intended primarily for the use 

 of students taking a practical laboratory 

 course in Embryology. The author's experi- 

 ence has led him to believe that the study of 

 carefully selected sections of embryos, accom- 

 panied by directions and explanations of the 

 significant structures in each section, offers 

 many advantages. This conviction has de- 

 termined the arrangement of the book. At- 

 tention is given chiefly to such points as serve 

 to explain adult anatomical relations, to illus- 

 trate general biological principles, and to 

 afford insight into pathological processes. 



Synopsis of Contents : General Concep- 

 tions. The Early Development of Mam- 

 mals. The Human Embryo. Study of Pig 

 Embryos. Study of Young Chick Embryos. 

 Study of the Blastodermic Vesicle and the 

 Segmentation of the Ovum. Study of the 

 Uterus and the Foetal Appendages in Man. 

 Methods. Index. 



" This new laboratory text-book of 

 Embryology is worthy of particular 

 attention. It is a practical guide of 

 a novel and original type, which is to 

 be recommended as a valuable aid in 

 laboratory teaching of a difficult na- 

 ture. It is a valuable addition to the 

 list of available text-books of Embry- 

 ology. In fact, the book stands by 

 itself and is an original departure in 

 a very desirable direction, introduc- 

 ing the student to the subject by a 

 practical method which promises ex- 

 cellent results. After a year's experi- 

 ence with it, we feel much confidence 

 in its success." Bulletin of the Johns 

 Hopkins Hospital.
